Answer:
Perfectly cube - shaped
Explanation:
If the shape of a cell is perfectly cube- shape then its volume must be calculated with an equation:
Height×Width×number of sides and number of boxes
Surface= area of volume ratio is calculated with an equation
Area /volume
if a cell has large surface area to volume into ratio means it has greater exposure to the environment.It means that flow of nutrients and gases move freely in the small cell compared to large cell.
A class of lipids used as chemical messengers, to signal cells to undergo changes, is called Monoglycerides. Its a class of glycerides which are composed of molecules of glycerol linked to fatty acid by easter bond.
Monoglycerides are the type of glyceride and that made up of glycerol and one fatty acid chain. Triglycerides are very similar expect they have three fatty acid chains. Mono and diglycerides may be manufactured through the reaction of plant or animal derived fatty acids with glycerol which breakdown plant or animals which derived fats and oils.
Lipids such as steroid hormones that serve as chemical messengers between cells , tissues and organs and other communicate signals between biochemical system within a single cell.

Answer:
When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.
Explanation:
You might expect that sheltered areas of stone buildings and monuments would not be affected by acid precipitation. However, sheltered areas on limestone and marble buildings and monuments show blackened crusts that have peeled off in some places, revealing crumbling stone beneath. This black crust is primarily composed of gypsum, a mineral that forms from the reaction between calcite, water, and sulfuric acid. Gypsum is soluble in water; although it can form anywhere on carbonate stone surfaces that are exposed to sulfur dioxide gas (SO2), it is usually washed away. It remains only on protected surfaces that are not directly washed by the rain.
Answer:
B. Puerperium, or fourth trimester of pregnancy
Explanation:
- Puerperium or the fourth trimester of pregnancy is also known as the postpartum period.
- This period starts immediately after the mother gives birth to a child.
- During this period the size of the uterus and other reproductive organs along with the hormone levels return to their normal state.
- It is the phase where regression of all the anatomical and physiological changes that took place i in the reproductive organs of the females takes place.
- This phase is divided int three periods -
1. Immediate puerperium, or the first 24 hours after parturition
2. Early puerperium, which extends until the first week postpartum;
3. Remote puerperium, which includes the period required for involution of the genital organs and return of menses, usually approximately 6 weeks.
- This phase is highly critical for the mother as this requires rest and proper care as there are risks of bleeding. Therefore, the midwife or the nurse must take proper care of the mother.
The hawk, a carnivore (animal meat-eater), is predating on the rabbit, an herbivore (plant-eater). So the hawk can be seen as the predator and the rabbit as the prey.
But another type of relationship important in Ecology is consumers. So producers are the plants that feed a food web. That makes the rabbits the primary consumers (herbivores) of these plants. Then the hawks become the secondary consumers (carnivores) of the primary consumers, by eating the herbivores.
Hope that this makes sense!
